Will the Saturn 4 be fine in an unheated garage?

Newbie here, planning on buying the Saturn 4 Ultra and I just wanted to make sure I have somewhere to put it. I don't have enough space or ventilation inside and I have pets, so that's a no-go. Will it be ok in an unheated detached garage? I know it comes with a cover to help keep a consistent internal temperature (I assume), so should I still use heaters to bring the garage up to room temp? Thanks. Any additional tips are welcome.
